A liquid extract made by steeping finished compost in water, containing beneficial microorganisms that suppress diseases and improve plant vigor when sprayed on foliage or soil.
Steep finished compost in water for 24-48 hours; strain and spray. The liquid contains beneficial bacteria and fungi that suppress soil diseases and improve plant health. It's less proven than solid compost but widely used in organic gardening. Quality depends on compost source (hot, finished compost best; immature compost less beneficial).
Compost tea provides beneficial microbes without adding bulk compost. It's useful for disease suppression and plant vigor without chemical inputs.
